To all wko/n it may concern:

Be it known that we, Annan M. SEELEY and AUGUST HUETHER, citizens ofthe United States, and residents of Newark, New Jersey, and Brooklyn, New York, have invented certain new and usei'qul Improvements in Automatic Tube-Cuttin Machines, of which the following is a speci cation, accompanied by drawings.

This invention relates to machines for cutting tubes, more particularly to an automatic machine for cutting paper tubes into lengths, and the objects of the invention are to improve upon the construction of such machines, increase their efficiency, reduce the wear and shock tothe parts in operation and prolong .the life of the machine.'

Further objects ot the invention will hereinafteil appear and to all of these ends the' invention consists of a machine-for cutting tubes embodying the features of construe'- tion, combinations of elements, and arrangement of parts substantially as hereinafter fully described and claimed in this specification and shown inl the accompanying drawings, in which- Figure 1 is a top plan view of a machine embodying the invention; Fig. 2' is a front elevation of the machine; Fig. 3 is an end elevation; Fig. 4 is an enlarged transverse sectional view on the line IV-IV of F-ig. -1 looking inthe direction of the arrows; Fig.

The paper tubes D to be cut are fed from the hopper E to the carriage B, and are carried over the mandrel C and cut into lengths by the cutter mechanism, after which the'cut sections of tube are stripped or removed from the mandrel and fall through the chute G to the receiver H.

The driving pulley J is loosely mounted on the main driving Ashaft L and is adapted to be connected to the driving shaft by suitable clutch mechanism. In this instance (see Figs. 8, 10 and 12) th`e pulley J is provided with a boss O on which is loosely mounted the split spring ring P, having the beveled toe Q. `Outside of this ring P is a casing -R fast to the shaft L and having a lever S pivotally mounted therein, the outer and longer curved end of which projects into proximity to the beveled sleeve T loose on the main shaft. A hand lever U, pivoted at V on a suitable bracket, engages an annular vgroove in the beveled sleeve T by means of the pin s hown, so that by operating the hand lever the shorter arm of the lever S may be moved into engagement with the beveled toe Q', in the obvious manner,

vthereby tightening the split ring P on the driving pulley. The said split ring operates under such conditions as a band clutch, being confined to revolve with the casing R by means of the extremity Y which abuts against an adjustable set screw Z 1n a cha-mber therein. The operation'of the hand lever U thus causes the shaft L to be clutched to the driving pulley for drivlngthe machine. On the outer end of the drlveshaft L is placed a hand wheel a by which the main shaft can be manually rotated.

The shaft L is suitably .supported 1n the toetsen YThe cross-shaft zv carries the cam 72 through which the tube carriage B, later described, is actuated. 1n the present instance this cani is a face cam formed with a cam-groove marked 0. rlhe connecting rod having a yoke-bearing y (Fig. 29) on the said shaft 71., is provided with a cam-stud fr' engaged in the cam-groove whereby the said rod is reciprocated as the cam `is revolved'. The other end of connecting rod j? is pivoted at s to the segment t hung on the stud u, as

'appears more clearly in Figs. 4, 5 and 7.

Segment t meshes with a short-radius segment '1- 'formed on the hub of a larger segment -g/ which is fast on across-shaft al. The teeth of the large segment mesh with the inverted rack z on the bottom of the tube carriage B. Rotation of the main driving shaft L transmits nio-tion through the worm and wheel f, g, and the cam 7c to the connecting rod p and thence through the segments t and y to the carriage Bin an obvious manner, impart-ing to the latter `a reciproca-ting motion corresponding to the design of the cam groove o. As shown more clearly in Fig. 29, the head portion 2 of the connecting rod p is provided with means to allow a certain amount of lost motion between the cam and the carriage, and this provision consti.- tutes an important feature of the present invention. The head 2 is formed as a sleeve on the end of rod 79 and has a lateral recess 3 containing a coil spring 4, surrounding the rod. One end of the spring thrusts against an adjustable abutment of the rod, in the form of a nut and 4lock nut 6 thereon, while the other Vend thrusts against the tubular portion 5 of the head. The nuts G serve to limit the inward thrust of the rod, by their engagement with the part 7. and outward movement is resisted by the elastic force of the spring 4. The yielding extensibility of the connecting rod that is thus afforded by the spring facilitates the movement of the carriage and at the same time. averts injury to the machine in case of accidental ob-V lvices, adapted to slow down the motion of the parts near each end of the reciprocation.

To this end we provide a braking mechanism, shown at 15 -in various figures of the drawings, applied to the shaft fw on which the main segment 3/ is mounted as above explained, although the saine or equivalent braking means could be applied to other parts ofthe described mechanism with similar eti'ect. As applied to the shaft fw, the

said device '(Figs 37 and 38) comprises a' hubor drum 14 fastened thereto and surrounded or embraced by two half-collars 16 and 1S with a leather friction ring or lining' 17 between the proximate surfaces of the drum and the surrounding parts. The friction ring 17 is clamped with some pressure upon the drum by the two bolts 17 the pressure or friction produced being variable 'by varying the degree to which the bolts are tightened. The two half collars are thus adapted to rock with the shaft lw and segment y, but the extent of their rocking movement is limited in both directions to an .arc less thantliat of the shaft and segment,

as for instance, by means of the fixed stud 19. which is alternately engaged by the opposite shoulders on the collar 18- as shown ln: Fig. 37. 'l` he motion of the segment and its operated parts is thus retarded by the a sprocket chain 40 with a corresponding friction of the drum `14 at each end of their sprocket 39 of the mandrel On one side the sprocket wheel 9 is v rovided with one of the members 10 of a riction clutch, the complementary clutch member 11, of which is splinedto the drive shaft and'v normally rpelled from the member 10 by the interposed coil spring 20L A collar 12 fast on ,the shaft L holds the sprocket from endwise movement. The annular groove 13 in the hub of the member A11 is engaged by a stud 23 of a lever 22, .the latter being from the frame on a stud bolt 21 and pivotally connected byj its free end to the end of an adjustable cam rod 24 of the cross shaft h above described, so that the said lever 22 may be appropriately operated to close the clutch member at the proper mo- .ment and thereby connect the mandrelC with the powershaft' forL operation thereby.

The cam rod 24 is adjustable in length by means of 'af right andleft handed nut 25 of well understood operation, and its terminal portion 26 is oked over the cross-shaft as asupport, an providedwith the cam stud or roller 29, by which it is reciprocated by the cam 27 on shaft h, all as clearly shown in Figs. 8, 9 and 11 of the drawings.

Themandrel C is removable from the machine so that it can be substituted by others of different lengths or diameters,'and its mounting for this purpose comprises a hollow spindle 35 which is journaled in the two uprights 34 with the driving sprocket 39 fast thereon between the bearings. The inner end ofthe spindle overliangs the inner bearing forming a head 36 (Fig. 8) which is recessed to receive the reduced end 37 of the mandrel C (Fig. .8), and the latter is held firmly in the recess and .against the face ofthe head 36 by means of a long, square-headed bolt 38 occupying or fitting the interior of the spindle. The operation of removing and installing the mandrel Will be apparent from a consideration of the drawings. The mandrel is covered with a .removable sleeve marked C which is adjustable thereon and forms a smooth backi upon which the paper tube rests While being cut by the several knives, thereby providing for the cutting of uniformly clean edges in all of the tube sections. ln

the event of wear of the backing-sleeve, resulting from the action ofv the cut-ters thereon forming creases. or grooves inthe sleeve, the latter is shifted along the mandrel so as to present a fresh smoothsurface' to the knives, a small set screw, appearing in Fig. 8, at the end of sleeve Cfbeing used to hold the sleeve in its newly adjusted position.

The ca'm controlled clntchingmechanism.,v

above described, is timed to operate, and start the rotation of the mandrel C, immediately upon the placing of the tube thereon by the tube carriage B, whereupon the knife mechanism for severing the tube is brought into action upon the tube. This mechanism is carried Aon a. longitudinal shaft 49 held in suitable bearings 50 on the machine frame which are provided with screw handles 51 for setting'the caps-of the bearings firmly upon the'shaft to prevent any undesirable looseness or play. The knife bar 47 'extends parallel to the shaft 49 being supported thereon by the two rocker arms 48 at or near the opposite ends ofthe said shaftas shown in Figs. 2 and 6. The knifel bar, whichis shown in larger scale in Fig. 30, is'formed with end 'gudgeons pivotally held in the upper ends of the rocker' arms 48, and on its reartlange itis provided with a pendant bracket 52 r carrying a pin 53.
